Samsung Feature, Use a 100mm lens with the GX-20, 007, Sizes for 35mm film and Size of Sensor

Feature

●The 14.60 effective Megapixel of SAMSUNG digital camera sensor. (High dynamic range.)

●Built-in Optical Image Stabilization (OIS) minimizes or prevents digital images from becoming blurred due to camera shake.

●Features an Auto-Focussensor with 11 focusing points. The central 9 are wide cross area sensors.

●Improved manual focusing using a viewfinder similar to a conventional 35 mm SLR camera, with 0.95x magnification. Also features a superimpose function in which the focus points on the viewfinder illuminate red.

●Features a large 2.7-inch LCD monitor with 230,000 pixels and a Brightness Adjusting function for high-precision viewing performance.

●The Large, High-Resolution LCD Monitor and clear menus make the camera Easy to Operate.

●The SP Coated Sensor minimises dust. Any Remaining dust can be removed with sensor clear function.

●You can select JPEG or RAW image format. Or you can select JPEG and RAW at the same time.

●This is a Dustproof and Damp Proof camera for safe outdoor shooting.

●Features a Digital Preview function for checking the image to ensure that the desired result is achieved.

●The comfort and flexibility of the continuous Liveview function directly on the LCD is available to users.

●The Picture Wizard function enables you to adjust image before shooting. You can create the image you desire by adjusting the colour tone, saturation, and contrast and so on.

The captured area (view angle) will differ between the GX-20 and 35mm SLR cameras even if the same lens is used because the format size for 35mm film and the sensor are different.

Sizes for 35mm film and Size of Sensor

35mm film: 36mm x 24mm

GX-20 sensor: 23.4mm X 15.5mm

Angles of view being equal, the focal length of a lens used with a 35mm camera must be approximately 1.5 times longer than that of GX-20. To get the equivalent angle of view for a full-frame 35mm camera, divide the focal length of the 35 mm camera by 1.5. (When you use the GX-20 for shooting.)

Example) To get the equivalent angle of view of a 150 mm lens on a full-frame 35mm camera, you will get “100,” dividing 150 by 1.5.

Use a 100mm lens with the GX-20.

The equivalent focal length on a full-frame 35 mm camera is calculated in a opposite way of calculation as follows:

Example) If 300mm lens is used with GX-20 300x1.5=450

Focal length is equivalent to 450mm lens on a 35mm camera.

ÄCalculation method used above is to help users understand products and the results may be different depending on the types of lenses or the shooting environment. Calculated focal length value is based on the difference between the 35 mm film format and camera sensor in size. (GX-20 was used as standard to compare.)
